openstack/nova - nova - OpenDev: Free Software Needs Free Tools

This introduces a new flag "quantum_use_dhcp=<boolean>" which indicates whether
or not to enable dhcp for all of the networks. If it is set then we start
dnsmasq (and provide it with the IP/MACs from Melange) similar to how this was
done in linux_net before.
Prior to this if you enabled dhcp then you would also get a gateway device..
some people may not want that so we now require that you specify the gateway
when creating the network in order to end up with a device that will act as a
gateway. If you're using Melange IPAM and you don't specify the gateway you
still end up with one because it doesn't allow you to not have one. This lays
the groundwork for the option of not having one in the future, at least :)
Also, fix quantum/melange ipam interaction
We now query for the subnets by net_id/vif_id instead of searching through all
the blocks to find the right one. Both of the allocate and deallocate for
instance calls are now using the vif_id -> network_id mapping instead of
searching the quantum networks. get_port_by_attachment was also changed to
take a net_id so that we don't have to search through all of the quantum
networks to find the corresponding port.

Currently the plugin uses httplib which does not handle redirects
natively. XenAPI plugins require Python 2.4+ so using httplib2
as far as I know is not a possibility.
(Patch Set 2) Oops, forgot to PEP8 before putting up for review.
(Patch Set 3) Updated logging to be more verbose as per Waldon

Many extensions wrapped exceptions manually with faults.Fault and ther
continues to be some confusion if it's necessary. This patch clears up
what faults.Fault does as well as documents that wsgi.Resource
automatically wraps webob.exc.HTTPException

With melange it will be possible to have overlapping cidrs so it would be
better to specify the uuid of the network to delete.

This changes more OSAPI tests to using their Controller directly, bypassing
the slow wsgi setup process.

This branch adds the ability to define a local JSON file that will hold
configuration information that the scheduler can use.
This dict will be passed into the filter and weighing functions so that
Operations can tweak the scheduler without having to bring down the scheduler
service.
Currently the polling time on the file is hardcoded at 5 minutes, but certainly
this could be made into a flag.
Next update will be to remove the host_filter and weighing_functions flags
and fix the scheduler to get these values from the config file.

With iptables v1.4.10 I'm running into an issue with the chain length of the
"nova-dhcpbridge-floating-snat" table (iptables it complaining that the name
is too long; 28 chars max). This shortens the name of that table.
